UNITED STATES PATENT JOHN HOWARD POSTON, OF EUFAULA, ALABAMA.

COTTON-CLEANER.

SPECIFICATION forming part of Letters Patent No. 339,464, dated April 6, 1886.

Application filed June 17,1885.

Renewed Mar, h 2, 1886.

To all whom it may concern:

Be it known that 1, JOHN HOWARD POSTON, a citizen of the United States, residing at Enfanla,in the county of Barbour and State of Alabama, have invented certain new and useful Improvements in Ootton-Gleaners,of which the following is a description.

This invention relates to cotton-gin mills; and its object is to withdraw the dust and dirt from the condenser and from the gin-room, whereby the lint is straightened out into better fiber and the gin-room is rendered healthier and more comfortable.

To this end my invention consists in the construction and combination of parts forming the cotton-cleaner, hereinafter described and claimed, reference being had to the accompanying drawing, which is a sectional elevation of a portion of a cottongiu house showing my invention.

A represents a cottongin of any usual construction, provided, as nsual,with acondenser in which a cylindrical screen, B, revolves contiuuall y. The ginned cotton passes over the said screen B, in order that the dust and dirt contained in the cotton may have an opportunity to fall out. By my invention the falling of the dust is aided by suction produced by a fan, D, placed below'the screen B, and communicating therewith both at the lower side and at the ends thereof by a passage, F. This passage is provided with a gate, G, by means of which the draft maybe regulated.

E is a dischargepipe leading from the fan to any convenient point for discharging the dust and dirt which are withdrawn from the cotton.

I is a pipe leading from the gin-room into the fan below the gate G, whereby the dustin the air may be drawn into the fan and discharged.

J is a gate in the pipe I, to close the same or to regulate the opening thereof.

By means of the gates G- and J, the Whole draft of the fan may be directed to either the condenser-chamber or to the gin-room, or the draft may be regulated to any degree or be entirely shut off from either passage. More of the dirt in the cotton will be extracted by this forcible draft than would be withdrawn where the mere weight of the dirt is trusted to for its Withdrawal.

Any style of fan or exhaust pump or blower may be used at 1), instead of the common fan shown.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

lhe combination, in a cotton-cleaner, of a revolving screen, an air-exhausting device, a passage leading therefrom to the said screen, a gate in the passage, another passage leading from the gin-room to the exhausting device, and a gate therefor, substantially as shown and described.

JOHN HOXVARD POSTON.
